CWE-1338 Base Rascunho

Improper Protections Against Hardware Overheating

This vulnerability occurs when a hardware device lacks sufficient safeguards to prevent dangerous temperature increases during operation.

Definição

What is CWE-1338?

This vulnerability occurs when a hardware device lacks sufficient safeguards to prevent dangerous temperature increases during operation.
All electronic devices generate heat as a byproduct of their operation. Faster processors and higher power draw create more thermal energy. Without built-in protections like temperature sensors, adequate cooling, or power throttling, this heat can build up uncontrollably. Malicious software can exploit this by forcing the hardware into high-performance states, deliberately triggering overheating to cause a temporary malfunction or permanent physical damage—a technique known as a thermal denial-of-service attack. The consequences extend beyond security, impacting device safety and long-term reliability. While similar issues exist for overvoltage or overcurrent conditions, overheating is uniquely tied to normal hardware activity. It's important to note that while these protections guard against operational heat, they do not address separate failure modes like battery malfunctions, which require their own mitigation strategies.

Como os atacantes a exploram

Trajeto do atacante passo a passo

  1. 1

    Malicious software running on a core can execute instructions that consume maximum power or increase core frequency. Such a power-virus program could execute on the platform for an extended time to overheat the device, resulting in permanent damage.

  2. 2

    Execution core and platform do not support thermal sensors, performance throttling, or platform-cooling countermeasures to ensure that any software executing on the system cannot cause overheating past the maximum allowable temperature.

  3. 3

    The platform and SoC should have failsafe thermal limits that are enforced by thermal sensors that trigger critical temperature alerts when high temperature is detected. Upon detection of high temperatures, the platform should trigger cooling or shutdown automatically.

Exemplo de código vulnerável

Vulnerable pseudo

A MITRE não publicou um exemplo de código para este CWE. O padrão abaixo é ilustrativo — consulte os Recursos para referências canónicas.

Vulnerável pseudo 
// Example pattern — see MITRE for the canonical references.
function handleRequest(input) {
  // Untrusted input flows directly into the sensitive sink.
  return executeUnsafe(input);
}
Exemplo de código seguro

Secure pseudo

Seguro pseudo 
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
  const safe = validateAndEscape(input);
  return executeWithGuards(safe);
}
What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Lista de verificação de prevenção

How to prevent CWE-1338

  • Architecture and Design Temperature maximum and minimum limits should be enforced using thermal sensors both in silicon and at the platform level.
  • Implementation The platform should support cooling solutions such as fans that can be modulated based on device-operation needs to maintain a stable temperature.
